MATHIAS R. KONDOLF, OF CYNWYD, PENNSYLVANIA, ASSIGNOR TO BOX BOABID PROD- UCTS COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF DELA- WARE- CONTAINER AND CLOSURE THEREFOR.

Application filed October 17, 1924( Serial No. 744,194.

My improvements are primarily designed to effect the secure attachment of a closure to a container to prevent pilferage and form a tight joint between the parts.

6 In the preferred embodiment of my invention, an opening in the larger end of a tapered receptacle is closed by a l1d hav1ng flaps thereon pressed against the inclined walls of the receptacle or container by a con- 10 strictiug band or hoop, which is preferably laced through the flanges and may be caught in notches in the container walls. I

The divergence of the container walls in the direction of the cover prevents movement of the fastening band in one direction and the engagement of the cover with the con tainer walls prevents movement of the band laced through the flaps of such cover in the opposite directions, so that the lid and flaps are held in close contact with the container walls. Gussets may be provided on the cover flaps and held in position by the constricting band to reenforce the corners of the containers and sheathe the notches therein.

The joint so formed is substantially air tight so that the containers are suitable for the transportation of powders and other fluids. Moreover the fastening means may be secured with either the cover or the container in the super-incumbent position. This adaptability renders my improvements particularly useful in packing fruit, vegetables, or pomiform articlesso as to provide an attractive display layer of larger area than the remainder of the pack and with the apices of its constituents in a regular plane. In such usage, the closure is used as a base or support for the initially deposited display layer in the formation of a tapered pack, the

container is telescoped over the completed pack and the constricting band is drawn up and fastened; the closure retaining the pack in the container while the package is. turned to bring the closure and display layer uppermost.

The characteristic features and advantages of my improvements will more fully appear from the following description and the accompanying drawings of illustrative 5 embodiments of my invention.

In the drawings, Fig. 1 is a perspective view of a flattened out closure comprised in myinvent-ion; Fig. 2 is a perspective view showing the application thereof to an inverted tapered container; Fig. 3 is a broken perspective View of a container with the closure uppermost; Fig. 4 is a sectional view taken on the line 44 of Fig. 3; Fig.

5 is a perspective view of spaced blanks from which the container is formed and showing 00 how the corner sections are rendered yielding to the band; Fig. 6 is a broken perspective view of a container with a modified form of closure and fastening .band applied thereto; Fig. 7 is a plan view of the perforated intermediate blank shown in Fig. 5, and Fig. 8 is a plan view of the modified form of cover and fastening band shown in F ig. 6.

The improved closure and fastening means comprised in my invention are preferably used in conjunction with a tapered reoe tacle or container having its mouth at its larger end and formedt by gluingtogether under pressure a plurality of blanks A, B and C (shown in Fig. 5 in process of being telescoped within one another). The intermediate blank or core B (shown in plan in Fig. 7) has apertures 6 formed in zones of the end walls B and side walls B" which when overlapped as shown in Fig. 5 form the corners of the intermediate layer of the completed container. In the completed container, the registering holes 25 at each corner of the core B are covered by the walls of the external blank A and the internal blank C, but provide soft or yielding spots where the container wall may be readily notched.

The closure for the container comprises a median section 1 closing the mouth of the container and a peripheral rim or apron overlapping the container walls, and preferably consisting of flaps 3 hinged to the section 1 along the score lines 2. The flaps contain apertures 4 through which is laced or threaded a tension member or peripheral band 5.

As illustrated in Figs. 1 to 4 inclusive, the band 5 may be constricted to tightl press the flaps 3 against the container wal s A by means of a tightener and catch journalled in a bushing 6 set in one of the flaps 3. The tightener preferably comprises a. bar bent to form a spindle loop 7 passing through the bushing 6 and arms 8 extending parallel to the outer surface of the flap and terminating in the latching fingers 10. A sheave 9 is sleeved on the spindle 7 and held thereon between the flap 3 and container wall A by the ends of the band 5 which pass through axial holes 11 in the sheave and through the spindle 7 Sockets 13 are formed in the flap 3 around the axis of the tightener and in the path of the detents 10, which automatically engage therein to prevent slackening of a taut band.

A tapered pack of fruit or other objects may be formed upon the section 1 within a flexible endless retainer D seated thereon, and a container telescoped over the pack and retainer, as' indicated in Fig. 2. By rotating the tightener arms 8 the ends of the band 5 are wound on the sheave 9 to constrict the band and draw the container and closure tightly together. The engagement of the fingers 10 in the sockets 13 prevents the slackening'of the band 5, which may be secured in taut condition by sealing the detents in their sockets.

The bite of the tightened Wire 5 against the parts of the blank A adjacent to the apertures b depresses such parts and forms notches or indentations b at the corners of the container for confining the band.

As illustrated in Figs. 6 and 8, the side flaps 3 are provided with gussets or tabs 3 for covering the notches Z2 and reenforcing the tops of the corners of the package, the free ends of the gussets being overlaid by the end flaps 3. The gussets, as well as the flaps,

are drawn tightly against the container by the fiat band 5 threaded therethrough and held taut by crimping together its ends within the clip. 14. The gussets 3 are, of course, equally applicable to the structure shown in Figs. 1 to 4. i The interlocking of the fastening band 5 in the notches I) is effected without rupturing either the outer or inner surface of the contalner, and the reenforcement afforded by the gussets 3 obviates any possibility of crushing the box corners or disengaging the band 5 from the notches. 7

Having described my invention, I claim:

1. The combination with a tapered contalner havmg an opening at its larger end, of a closure having a rim including a band surrounding said container between the larger and smaller ends thereof and forming, when fastened, an inexpansible constricting devlce of smaller perimeter than the perimeter of said container opening and non-detachably secured to said rim, securing said run to said container. 7

2. The combination with a tapered c0ntamer, of a closure therefor having flaps movable independently of one another, and

a band substantially parallel with the free edge/of sald flap for securing said flap against said container without passing therethrough, said closure being detachable from said container without removing said band from said closure.
